Wonderful Balloon Ascents Part 2

The inflation with hydrogen was effected in a very curious manner. As much as 1,125 lbs. of iron and 560 lbs. of sulphuric acid were found necessary to inflate a balloon which had scarcely a lifting power of 22 lbs., and the process of filling took no less than four hours. At length, however, at the end of the fourth hour, the balloon, composed of strips of silk, coated with varnish, floated, two-thirds full, from the workshop of the brothers Robert.

On the morning of the 26th of August, the day before the ascent was to be made, the balloon was visited at daybreak, and found to be in a promising state. At two o'clock on the following morning its constructors began to make preparations to transport it to the Champ de Mars, from which place it was to be let loose. Skilled workmen were employed in its removal, and every precaution was taken that the gas with which it was charged should not be allowed to escape. In the meantime the excitement of the people about this wonderful structure was rising to the highest pitch. The wagon on which it was placed for removal was surrounded on all sides by eager mult.i.tudes, and the night-patrols, both of horse and foot, which were set to guard the avenues leading to where it lay, were quite unable to stem the tide of human beings that poured along to get a glimpse of it.

The conveyance of the balloon to the Champ de Mars was a most singular spectacle. A vanguard, with lighted torches, preceded it; it was surrounded by special attendants, and was followed by detachments of night-patrols on foot and mounted. The size and shape of this structure, which was escorted with such pomp and precaution--the silence that prevailed--the unearthly hour, all helped to give an air of mystery to the proceedings. At last, having pa.s.sed through the princ.i.p.al thoroughfares, it arrived at the Champ de Mars, where it was placed in an enclosure prepared for its reception.

When the dawn came, and the balloon had been fixed in its place by cords, attached around its middle and fixed to iron rings planted in the earth, the final process of inflation began.

The Champ de Mars was guarded by troops, and the avenues were also guarded on all sides. As the day wore on an immense crowd covered the open s.p.a.ce, and every advantageous spot in the neighborhood was crowded with people. At five o'clock the report of a cannon announced to the mult.i.tudes, and to scientific men who were posted on elevations to make observations of the great event, that the grand moment had come. The cords were withdrawn, and, to the vast delight and wonder of the crowd a.s.sembled, the balloon shot up with such rapidity that in two minutes it had ascended 488 fathoms. At this height it was lost in a cloud for an instant, and, reappearing, rose to a great height, and was again lost in higher clouds. The ascent was a splendid success. The rain that fell damped neither the balloon nor the ardor of the spectators.

This balloon was 12 feet in diameter, 38 feet in circ.u.mference, and had a capacity of 943 cubic feet. The weight of the materials of which it was constructed was 25 lbs., and the force of ascension was that of 35 lbs.

The fall of the balloon was caused by the expansion and consequent explosion of the hydrogen gas. This event took place some distance out in the country, close to a number of peasants, whose terror at the sight and the sound of this strange monster from the skies was beyond description. The people a.s.sembled, and two monks having told them that the burst balloon was the hide of a monstrous animal, they immediately began to a.s.sail it vigorously with stones, flails, and pitchforks. The cure of the parish was obliged to walk up to the balloon to rea.s.sure his terrified flock. They finally attached the burst envelope to a horse's tail, and dragged it far across the fields.

Many drawings and engravings of the period represent the peasants armed with pitchforks, flails, and scythes, a.s.sailing it, a dog snapping at it, a garde-champetre firing at it, a fat priest preaching at it, and a troop of young people throwing stones at the unfortunate machine.

The news of this fiasco came to Paris, but too late. When search was made for the covering, scarcely a fragment could be found.

A somewhat humorous result of all this was the issue of a communication from government to the people, ent.i.tled, "Warning to the People on kidnapping Air-balloons." This doc.u.ment, duly signed and approved of, describes the ascents at Annonay and at Paris, explains the nature and the causes of the phenomena, and warns the people not to be alarmed when they see something like a "black moon" in the sky, nor to give way to fear, as the seeming monster is nothing more than a bag of silk filled with gas.

This first ascent in Paris was an important event. Every one, from the smallest to the greatest, was deeply interested in it, while to the man of science it was one of the most exciting of incidents. For the purpose of observing the alt.i.tude to which the balloon rose, and the course it took, Le Gentil was on the observatory, Prevost was on one of the towers of Notre Dame, Jeaurat was on La Place Louis XV., and d'Agelet was on the Champ de Mars. It was only Lalande that frowned as he witnessed the success of the experiment. He had predicted the year before that air-navigation was impossible.

Chapter VI. Third Experiment.

(Montgolfier's Balloon, Paris, Faubourg St. Antoine.)

As we have seen, the triumph of aerostation was sudden and complete. The young Montgolfier had arrived in Paris prior to the experiment of the 27th of August, and was present as a simple spectator on that occasion.

immediately afterwards he set to work upon a balloon, which was to be made use of when the Academy should investigate the phenomenon at Versailles in presence of the king, Louis XVI.

It was at this time (September, 1783) that those small balloons, made of gold-beaters' skin, which are used as children's toys to the present day, were first made. The whole of Paris amused itself with them, repeating in little the phenomenon of the great ascent. The sky of the capital found itself all at once traversed by a mult.i.tude of small rosy clouds, formed by the hand of man.

Faujas de Saint Fond says that at first an attempt was made to construct balloons of fine, light paper; but this material being permeable, and the gas being inflammable, balloons thus made did not succeed. It was necessary to seek a material less porous, and, if possible, still lighter.

The Journal de Paris, of the 11th of September, 1783, informed the public that the Baron de Beaumanoir, "who cultivated the sciences and the fine arts with as much success as zeal," would send up a balloon eighteen inches in diameter. At noon of the same day he made this experiment in presence of a numerous a.s.sembly in the garden in front of the Hotel de Surgeres.. The little balloon mounted freely, but was held in, like a kite, by means of a silk thread. In the course of the same afternoon, the baron took down the balloon and filled it anew with hydrogen, and then let it off. The spectators had the pleasure of seeing it rise to a great height, and pa.s.s away in the direction of Neuilly, and it is said to have been found at a distance of several leagues, by peasants.

However trifling this experiment may appear at first sight, it added a new fact to the science of aerostation. The material employed by the baron was lighter and better than paper. It was what is called gold-beaters' skin. This skin is simply the interior lining of the large bowel of the ox. It is carefully prepared, is relieved of the fat, stringy and uneven parts, is dried, and is afterwards softened. Little balloons of this material came to be the fashion, and they are still frequently seen.

At the same time, Montgolfier was busy constructing, at the request of the Academy of Sciences, a balloon seventy feet high and forty in diameter, with which it was proposed to repeat the experiment of Annonay. He took up his quarters in the magnificent gardens of his friend Reveillon, proprietor of the royal manufactory of stained paper in the Faubourg St. Antoine. The new balloon was of a very singular shape: the upper part represented a prism, twenty-four feet high the top was a pyramid of the same height; the lower part was a truncated cone, twenty feet in depth. It was made of packing-cloth, lined with good paper, both inside and out.

The gossipping and prolix Faujas de Saint Fond thus describes this machine:--"It was painted blue, represented a sort of tent, and was richly ornamented with gold Its height was seventy feet; its weight 1,000 lbs.; the air which it displaced was 4,500 lbs. in volume, and the vapor with which it was filled was half the weight of ordinary air. The approach of the equinox having brought rain, all the conditions under which this balloon was constructed and exhibited were unfavourable. The structure was so large that it was impossible to get it together and st.i.tch it, except in the open air--in the garden, in fact, where Montgolfier commenced its construction. It was a great labour to turn and fold this heavy covering, while the liability of the thick paper to crack was an additional difficulty. Not less than twenty men were required to move it, and they were obliged to use all their skill, and every precaution, not to destroy it. No balloon had ever given so much trouble. On the 11th of September the weather improved, and the balloon was entirely completed and prepared for the first experiment. In the evening the attempt was made. It was with admiration that the beholders saw the beautiful machine filling itself in the short s.p.a.ce of nine minutes, swelling out on all sides and showing the full symmetry of its artistic form. It was firmly held in hand, or it would have risen to a great height. On the following day the actual ascent was to take place, and the commissioners of the Academy of Sciences were invited to be present. In the morning thick clouds covered the horizon, and a tempest was expected; but as there was an ardent desire that the ascent should take place without delay, and as all the gearing was in order, it was resolved to proceed.

"Fifty pounds of dry straw were fired in parcels under the balloon, and upon the fire were thrown at intervals several pounds of wool. This fuel produced in ten minutes such a volume of smoke that the huge balloon was speedily filled. It rose, with a weight of 500 lbs. holding it down, to some height above the ground, and had the ropes by which it was attached to the ground been cut, it would have mounted to a great height.

Meantime the storm broke, rain descended, and the wind blew with great force. The most likely means of saving the balloon was to let it fly but as it was to ascend again on another occasion, at Versailles, the greatest efforts were made to bring it down, and these, together with the damage caused by the storm, eventually rent it into numberless fragments and tatters. It withstood the storm for twenty-four hours; then, however, the paper came peeling off, and this beautiful structure was a wreck."

Chapter VII. Fourth Experiment.

(Versailles, 19th September, 1783, in presence of Louis of XVI.)

Of course another balloon was wanted for the fete at Versailles. The king had demanded an ascent for the 19th, a week after the disaster at the Faubourg St. Antoine. Already the possibility of a man going up with the balloon was discussed, and people indulged in visions of splendid aerial trips; but the king would not hear of the proposal. Balloons were novelties, not offering sufficient security, and he was unwilling that any of his subjects should risk their lives in attempting the unknown.

He consented, however, to a proposal that animals might be sent up in the first instance, by way of experiment, suspended in an osier cage attached to the neck of the balloon.

Montgolfier at once began a new balloon. A few days only were at his disposal; but, a.s.sisted by friends, he worked with such ardour and success that he was able, on the date appointed, to produce a magnificent spherical balloon, much stronger than the former, constructed of good strong cotton cloth, and painted in distemper.

It is proper here to remark that the first balloons were much more elegant in appearance than those afterwards made. The coloured prints and engravings of the period enable us to form an opinion of the splendour of their ornamentation and the beauty of their design.

Sometimes the figures painted upon them represented scenes from the heathen mythology, and sometimes historical scenes; while rich embroideries, royal insignia, and gaily-coloured draperies added much to the general effect. The Versailles balloon was painted blue, with ornaments of gold, and it presented the form of a richly decorated tent.

It was fifty-seven feet in height, and sixty-seven in diameter.

It was first tried at Paris, and succeeded perfectly. On the morning of the 19th it was carried to Versailles, where due preparation had been made for its reception In the great court of the castle a sort of theatre had been temporarily erected with a scaffolding, covered throughout with tapestry In the middle was an opening more than fifteen feet in diameter, in which was spread a banquet for those who had constructed the balloon. A numerous guard formed a double cordon around the structure. A raised platform was used for the fire by means of which the balloon was to be inflated; a covered funnel or chimney of strong cloth, painted, was suspended over the fire-place, and received the hot smoke as it arose. Through this funnel the heated air ascended straight up into the balloon.

At six in the morning, the road from Paris to Versailles was covered with carriages. Crowds came from all parts, and at noon the avenues, the square of the castle, the windows, and even the roofs of the houses, were crowded with spectators. The n.o.blest, the most ill.u.s.trious, and most learned men in France were present, and the splendour of the scene was complete when their majesties and the royal family entered within the enclosure, and went forward to inspect the balloon, and to make themselves familiar with the preparations for the ascent.

In a short time the fire was lit, the funnel extended over it, and the smoke rose inside, while the balloon, unfolding, gradually swelled to its full size, and then, drawing after it the cage, in which a sheep and some pigeons were enclosed, rose majestically into the air. Without interreruption, it ascended to a vast height, where, inclining toward the north, it seemed to remain stationary for a few seconds, showing all the beauty of its form, and then, as though possessed of life, it descended gently upon the wood of Vaucresson, 10,200 feet from the point of its departure. Its highest elevation, as estimated by the astronomers Le Gentil and M. Jeaurat, Jeaurat, was about 1,700 feet.

Chapter VIII. Men and Balloons.

It is not natural that the human mind should stop upon the way to the solution of a problem, especially when it seems to be on the point of arriving at a satisfactory conclusion to its labours. The osier cage of Versailles very soon transformed itself into a car, bearing human pa.s.sengers, and the age of the "Thousand and One Nights" was expected to come back again. It was resolved to continue experiments, with the direct object of finding out whether it was impossible or desperately dangerous for man to travel in balloons. Montgolfier returned from Versailles, and constructed a new machine in the gardens of the Faubourg St. Antoine. It was completed on the 10th of October Its form was oval, its height 70 feet, its diameter 46 feet and its capacity 60,000 cubic feet. The upper part, embroidered with fleurs-de-lis, was further ornamented with the twelve signs of the zodiac, worked in gold. The middle part bore the monogram of the king, alternating with figures of the sun, while the lower part was garnished with masks, garlands, and spread eagles. A circular gallery made of osiers and festooned with draperies and other ornaments, was attached by a set of cords to the bottom of the structure. The gallery was three feet wide, and was protected by a parapet over three feet in height. It did not in any way interfere with the opening at the neck of the balloon, under which was suspended a grating of iron wire upon which the occupants of the gallery, who were to be provided with dried straw and wool, could in a few minutes kindle a fire and create fresh smoke, when that in the balloon began to be exhausted. The machine weighed, in all, 1,600 lbs.

The public had previously been warned, in the Journal de Paris de Paris, that the approaching experiments were to be of a strictly scientific character; and as they would be only interesting to savants, they would not afford amus.e.m.e.nt for the merely curious. This announcement was necessary, to abate in some degree the excitement of the people until some satisfactory results should be obtained; it was also necessary for those engaged in the work, whose firmness of nerve might have suffered from the enthusiastic cries of excited spectators. On Wednesday, the 15th of October, Pilatre des Roziers, who had on other occasions given proofs of his intelligence and courage in performing dangerous feats, and who had already signalised himself in connection with balloons, offered to go up in the new machine. His offer was accepted; the balloon was inflated; stout ropes, more than eighty feet long, were attached to it, and it rose from the ground to the height to which this tackle allowed it. At this elevation it remained four minutes twenty-five seconds; and it is not surprising to hear that Roziers suffered no inconvenience from the ascent. What was really the interesting thing in this experiment was, that it showed how a balloon would fall when the hot air became exhausted, this being the point which caused the greatest amount of disquietude among men of science. In this instance the balloon fell gently; its form distended at the same time, and, after touching the ground, it rose again a foot or two, when its human pa.s.senger had jumped out.

On Friday, the 17th of October, this experiment was repeated, and the excitement of the public on this occasion was unbounded. "All the world"

came to see. Roziers was again lifted up in the balloon, to the height of eighty feet; but so strong was the wind, and the strain on the ropes was so great, that the balloon was somewhat unsteady, and the exhibition was not on the whole such a splendid success as that of the preceding Wednesday.

On Sunday, Montgolfier chose a fine day for the following ascents:--"First Ascent: On the 19th of October, 1783, at half-past four, in presence of two thousand spectators, 'the machine' was filled with gas in five minutes, and Roziers, being placed in the gallery with a counterbalancing weight of 110 lbs. in the other side of the gallery, was carried up to the height of 200 feet. The machine remained six minutes at this elevation without any fire in the grating. Second Ascent: The machine carried Roziers and the counterbalancing weight--fire being in the grating--to the height of 700 feet. At this height it remained stationary eight and a half minutes As it was drawn back, a wind from the east bore it against a tuft of very tall trees in a neighbouring garden, where it got entangled, without, however, losing its equilibrium. The gas was renewed by Roziers, and the balloon again rising, extricated itself from among the branches, and soared majestically into the air, followed by the acclamations of the public.

This second ascent was very instructive, for it had been often a.s.serted that if ever a balloon fell upon a forest it would be destroyed, and would place those who travelled in it in the greatest peril. This experiment proved that the balloon does not FALL it DESCENDS; that it does not overturn; that it does not destroy itself on trees; that it neither causes death, nor even damage, to its pa.s.sengers; that, on the contrary, the latter, by making new gas, give it the power of detaching itself from the trees; and that it can resume its course after such an event. The intrepid Roziers gave in this ascent a further proof of the facility he had in descending and ascending at will. When the machine had risen to the height of 200 feet it began to descend lightly, and just before it came to the earth the aeronaut very cleverly and quickly threw on more fuel and produced more smoke, at which the balloon, to the astonishment of every one, suddenly soared away again to its former elevation. Third Ascent: The balloon rose again with Roziers, accompanied this time by another aeronaut, Gerond de Villette; and as the cords had been lengthened, the adventurers were carried up to the height of 324 feet. At this elevation the balloon rested in perfect equilibrium for nine minutes. It was the first time that human beings had ever been carried to an equal elevation, and the spectators were astonished to find that they could remain there without danger and without alarm. The balloon had a superb effect at this elevation; it looked down upon the whole town, and was seen from all the suburbs. Its size seemed hardly diminished in the least, though the men themselves were barely visible. By the aid of gla.s.ses, Roziers could be seen calmly and industriously making new gas. When the balloon descended the two men declared that they had not experienced the slightest inconvenience from the elevation. They received the universal applause which their zeal and courage so well deserved. The Marquis d'Arlandes, a major of infantry, afterwards went up with Roziers, and this latter experiment was as successful as the former."

Some days after these experiments the conductors of the Journal de Paris who described them, received a letter from Montgolfier, and also one from Gerond de Villette. The latter only is of interest here. Gerond de Villette says: "I found myself in the s.p.a.ce of a quarter of a minute raised 400 feet above the surface of the earth. Here we remained six minutes. My first employment was to watch with admiration my intelligent companion. His intelligence, his courage and agility in attending to the fire, enchanted me. Turning round, I could behold the Boulevards, from the gate of St. Antoine to that of St. Martin, all covered with people, who seemed to me a flat band of flowers of various colours. Glancing at the distance, I beheld the summit of Montmartre, which seemed to me much below our level. I could easily distinguish Neuilly, St. Cloud, Sevres, Issy, Ivry, Charenton, and Choisy. At once I was convinced that this machine, though a somewhat expensive one, might be very useful in war to enable one to discover the position of the enemy, his manoeuvres, and his marches; and to announce these by signals to one's own army. 1 believe that at sea it is equally possible to make use of this machine.

These prove the usefulness of the balloon, which time will perfect for us. All that I regret is that I did not provide myself with a telescope."

Chapter IX. The First Aerial Voyage--Roziers and Arlandes.

These experiments had only one aim--the application of Montgolfier's discovery to aerial navigation. The knowledge gained in the Faubourg St. Antoine having led to the most favourable conclusions, it was resolved that a first aerial voyage should be attempted.

"If," says Linguet, "there existed an autograph journal, written by Columbus, descriptive of his first great voyage with what jealous care it would be preserved, with what confidence it would be quoted! We should delight to follow the candid account which he gave of his thoughts, his hopes, his fears; of the complaints of his followers, of his attempts to calm them, and, finally, of his joy in the moment which, ratifying his word and justifying his boldness, declared him the discoverer of a new world All these details have been transmitted to us, but by stranger hands; and, however interesting they may be, one cannot help feeling that this circ.u.mstance makes them lose part of their value."

The narrative of the first aerial voyage, written by one of the two first aeronauts, exists, and we are in a position to place it before our readers. Such an enterprise certainly demanded great courage in him who was the first to dare to confide himself to the unknown currents of the atmosphere It threatened him with dangers, perhaps with death by a fill, by fire, by cold, or by straying into the mysterious cloud-land. Two men opposed the first attempt. Montgolfier temporised, the king forbade it, or rather only gave his permission on the condition that two condemned criminals should be placed in the balloon! "What!" cried Roziers, in indignation at the king's proposal, "allow two vile criminals to have the first glory of rising into the sky! No, no; that will never do!"

Roziers conjured, supplicated, agitated in a hundred ways for permission to try the first voyage. He moved the town and the court; he addressed himself to those who were most in favour at Versailles; he pleaded with the d.u.c.h.ess de Polignac, who was all-powerful with the king. She warmly supported his cause before Louis. Roziers dispatched the Marquis d'Arlandes, who had been up with him, to the king. Arlandes a.s.serted that there was no danger, and, as proof of his conviction, he offered himself to accompany Roziers. Solicited on all sides, Louis at last yielded.

The gardens of La Muette, near Paris, were fixed upon as the spot from which this aerial expedition should start. The Dauphin and his suite were present on the occasion. It was on the 21st of October, 1783, at one o'clock p.m., that Roziers and Irelands took their leave of the earth for the first time. The following is Arlandes' narrative of the expedition, given in the form of a letter, addressed by the marquis to Faujas de Saint Fond:--"You wish, my dear Faujas, and I consent most willingly to your desires, that, owing to the number of questions continually addressed to me, and for other reasons, I should gratify public curiosity and fix public opinion upon the subject of our aerial voyage.

"I wish to describe as well as I can the first journey which men have attempted through an element which, prior to the discovery of MM.

Montgolfier, seemed so little fitted to support them.

"We went up on the 21st of October, 1783, at near two o'clock, M.
